The locking mechanism 18 includes a first locking structure 182, a second locking structure 184, a manipulation part 186, a third locking structure 188, a fourth locking structure 190, and a return spring 192. The first locking structure 182 is disposed on the electronic-device casing 14. The second locking structure 184 is disposed on the door 16. The manipulation part 186 is disposed on the apparatus casing 12 to be capable of moving relative to the apparatus casing 12. The third locking structure 188 is connected to the manipulation part 186 and capable of being engaged with the first locking structure 182. The fourth locking structure 190 is connected to the manipulation part 186 and capable of being engaged with the second locking structure 184. The return spring 192 urges against and between the manipulation part 186 and a rib 126 of the apparatus casing 12 so as to drive the manipulation part 186 back to a locking position.

In embodiment, the first locking slot extends in a first direction D1. The electronic-device casing 14 is engaged or disengaged with the apparatus casing 12 parallel to a second direction D2. The second direction D2 is perpendicular to the first direction D1. Therefore, after the first latch is inserted into the first locking slot, the electronic-device casing 14 can be prevented efficiently from being disengaged from the apparatus casing 12. It is added that the first latch has an oblique surface 1882 at its front end. When the electronic-device casing 14 is engaged with the apparatus casing 12 along the second direction D2, the electronic-device casing 14 can push the oblique surface 1882 to retract the first latch back. Then, when the electronic-device casing 14 is moved to a locking position, the first latch is to be inserted into the first locking slot by use of the resilience by the return spring 192 so as to finish the engagement between the electronic-device casing 14 and the apparatus casing 12. However, the invention is not limited to the case of the first latch with the oblique surface 1882 at its front end.
Furthermore, the second locking slot extends in a third direction D3. The door 16 is engaged or disengaged with the apparatus casing 12 in a fourth direction D4. The fourth direction D4 is perpendicular to the third direction D3. Therefore, after the second latch is inserted into the second locking slot, the door 16 can be prevented efficiently from being disengaged from the apparatus casing 12. It is added that in a practical engagement of the door 16 with the apparatus casing 12, three tenons 162 of the door 16 are first inserted into three locking slots 1242 of the apparatus casing 12 at the edge of the opening 124, and the door 16 is then rotated till the opening 124 is covered completely. Therefore, in practice, the second locking slot approaches the second latch in a curve path. The movement direction of the second locking slot can be regarded as the direction perpendicular to the third direction D3, when the second locking slot is quite close to the second latch. In the embodiment, for simple illustration, the fourth direction D4 is still taken as the direction of the door 16 being engaged with the apparatus casing 12. In addition, the second latch also has an oblique surface 1902 at its front end. When the door 16 is engaged with the apparatus casing 12 along the fourth direction D4, the second locking structure 184 can push the oblique surface 1902 to retract the second latch back. Then, when the door 16 covers the opening 124 completely, the second latch is to be inserted into the second locking slot by use of the resilience by the return spring 192 so as to finish the engagement between the door 16 and the apparatus casing 12 . However, the invention is not limited to the case of the second latch with the oblique surface 1902 at its front end.
It is added that in the embodiment, the third direction D3 is identical to the first direction D1, so the manipulation part 186 can be designed to be moved parallel to the first direction D1 for simple mechanism. Furthermore, in the embodiment, the fourth direction D4 is perpendicular to the second direction D2, which is due to a common design for notebook; that is, the battery module is usually inserted from a side. However, the invention is not limited to it. In addition, there is a gap existing between the second latch and the apparatus casing 12. In practice, the second latch can be disposed closer to the apparatus casing 12 to enhance the engagement strength between the second latch and the second locking slot. It is added more that in practice, the locking mechanism for the battery module is usually disposed symmetrically. In the embodiment, the casing structure 1 also includes another locking mechanism 19 opposite to the locking mechanism 18 for locking the electronic-device casing 14. In practice, if the coverage of the door 16 spreads close to the locking mechanism 19, the locking mechanism 19 can lock the door 16 together with the locking mechanism 18.
As discussed above, based on the characteristics of the locking mechanism of the invention, when the door 16 is engaged with the apparatus casing 12 and covers the opening 124, and the electronic-device casing 14 is engaged with the apparatus casing 12, the manipulation part 186 is capable of being manipulated such that the third locking structure 188 and the fourth locking structure 190 are engaged with the first locking structure 182 and the second locking structure 184 respectively and simultaneously so as to lock the door 16 and the electronic-device casing 14; when the door 16 and the electronic-device casing 14 have been locked by the locking mechanism 18, the manipulation part 186 is capable of being manipulated such that the third locking structure 188 and the fourth locking structure 190 are disengaged from the first locking structure 182 and the second locking structure 184 respectively and simultaneously so as to unlock the door 16 and the electronic-device casing 14. After the unlocking, a user can detach the electronic-device casing 14 and the door 16 and then maintain or change the internal electronic device 2 in the accommodating space 122. In other words, the user can manipulate the manipulation part 186 to unlock the engagement of the two components with the apparatus casing 12 simultaneously, which saves time efficiently and solves the complicated opening operation on the casing in the prior art.
In the above embodiment, the second locking slot is a hole, but the invention is not limited to it. Please refer to

In the above embodiments, the locking mechanisms perform the locking and unlocking mechanism by linear movement, but the invention is not limited to it. Please refer to
As discussed above, the locking mechanism of the invention can lock or unlock two casings (such as a removeable battery module and a bottom door) engaged with the apparatus casing at the same time. Therefore, a user can detach the battery module and the door quickly so as to safely maintain or change the components disposed in the apparatus casing, which solves the problem in the prior art that maintaining internal electronic components needs to perform the complicated opening operation on the casing first. Furthermore, because the locking mechanism of the invention can lock or unlock two casings engaged with the apparatus casing at the same time, the invention is conducive to reducing the quantity of the locking mechanisms disposed in the whole casing structure.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
